ABSTRACT
Most people think of single-lens reflex cameras (SLRs) as complicated cameras that
only gadget geeks and professional photographers know how to use. Nothing could
be further from the truth. There was a time when using an SLR meant that you had
to learn a lot of unfamiliar terms and think about so many factors that you would get
very few photos at all, and frequently the pictures that you got back from the photo lab
were not very good.
